現說明第二步驟。The nozzle N is provided on the bottom side of the nozzle holder 22. The nozzle N is positioned between the first sensor support 24a and the second sensor support 2A. Liquid crystal droplet D Figure 3 shows that the liquid crystal droplet passes between the emitting portion 25a of Fig. 2 and the receiving portion 2. As shown in Fig. 3, the liquid crystal droplets are emitted from the nozzle N. The liquid crystal droplet passes between the emitting portion 25a and the receiving portion 25b. 10 201031468 The sensor 25 obtains a sensing value by detecting liquid crystal droplets passing between the transmitting portion 25a and the receiving portion 25b. The sensed value indicates the amount of light received by the receiving unit 25b from the transmitting unit 25& When the liquid crystal droplet passes between the emitting portion 25a and the receiving portion 25b, the light passes through the liquid crystal droplet passing between the emitting portion 25a and the receiving portion 25b, and proceeds from the emitting portion 25a into the j receiving portion 25b. As a result, the amount of light received by the receiving portion 25b is smaller than the amount of light when the light does not travel through the liquid crystal droplets. At this time, the sensor 25 transmits a signal to the control unit (when the control unit receives the signal from the sensor 25, the control unit recognizes that the liquid crystal droplet is emitted from the nozzle N. The input unit inputs the coating head unit 20 through the nozzle N. The initial speed of coating the liquid crystal amount. (10) Lai Shu Rong screen, key Figure 4 shows that the liquid crystal droplets remain in the nozzle hole of the nozzle of Figure 2 and are not emitted from the nozzle ν. Figure 5 is a diagram showing the experimental data to show The speed of the coated liquid crystal increases, and the sensor transmits a signal to the control unit. Figure 7 is a flow chart of the first method according to the present invention for determining the nozzle from the nozzle 11 201031468 - the liquid crystal droplet falls on the mother The appropriate method is to break the area without the proper speed. The first method is now described, thereby determining the appropriate speed at which the coating head unit coats the amount of liquid crystal. The initial speed is assumed to be 4.8 m/s. The initial speed can be greater or less than 4.8 m. /s. Set the fixed value to f. The solid particle can be greater than or less than i 6m / s. Also assume that the weight of the liquid crystal droplet is 〇.5mg. The weight of the liquid crystal droplet can be greater than or less than 〇.5mg. Also assume that the nozzle is inside (four) 0.2 The position of the nozzle Chen Ke is less than 〇2mm. The input unit inputs the initial speed of the liquid crystal amount of the coating head unit 2 through the nozzle N by 4.8 m/s. The input unit inputs a fixed value Lews. ^ The measuring unit detects the liquid crystal droplets emitted from the nozzle N. Let the detecting unit be the sensor 25. Referring to Figure 7 'When the debt measuring unit does not detect the initial liquid crystal droplet %, the control unit performs: step Μ 'by adding the initial speed to the fixed value, Obtaining a temporary speed; step 1-2, instructing the coating head unit 2 to apply a liquid crystal amount through the nozzle N at a temporary speed; and step 丨_3, when the detecting unit detects the liquid crystal droplet, 'determining the temporary speed to an appropriate speed 12 201031468 When the detection unit does not face the liquid crystal droplet at the temporary speed, the control unit repeats = step I·2, and the towel repeats the step by replacing the initial speed with the initial speed of the number of the marriage value. I_2, until the _ unit gamma = crystal droplet, and decides to detect the temporary speed of the liquid crystal droplet to the appropriate speed. When the detecting unit detects the liquid crystal droplet at the initial speed, the control unit performs: Step 2-1, borrow By subtracting the initial speed from the solid Setting a value to obtain a temporary speed; Step 2-2, instructing the coating head unit 2 to apply a liquid crystal volume through the nozzle at a temporary speed; and Step 2·3 'When the thin unit does not detect a liquid crystal droplet of a temporary speed The initial speed is determined to be an appropriate speed. When the detecting unit detects the liquid crystal droplet of the temporary speed, the control unit repeats step 2-2, wherein the initial speed is subtracted from the temporary speed by a fixed number of times to replace the temporary speed, and the step 2 is repeated. -2, until the detection unit does not detect the liquid crystal drop. Then, it is determined that the last temporary speed when the liquid crystal droplet is detected is the appropriate speed. As shown in Fig. 4 and Fig. 5, when the coating head unit 2 is in the initial stage Speed 4.8 m/s When the liquid crystal amount is applied, the liquid crystal droplets remain in the orifice of the nozzle N and are not emitted from the nozzle N. In this case, as shown in Fig. 5, no liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 does not transmit a signal to the control unit. As a result, the control unit determines that the liquid crystal droplets are not emitted from the nozzle N. Step 1-1 will now be explained. 13 201031468 lfm/s and obtain the temporary control unit with an initial speed of 4.8m/s plus a fixed value of 6.4m/s.步骤Description Step 1_2 The cloth head unit 20 instructs the N coating liquid crystal amount through the nozzle control unit at a temporary speed of 6.4 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle n before applying the liquid crystal amount through the nozzle N. Now explain steps 1-3. As shown in Figs. 3 and 5, when the coating head unit 20 applies a liquid crystal amount at a temporary speed of 6.4 m/s, the liquid crystal droplets are emitted from the nozzle N and pass between the emitting portion 25a and the receiving portion 25b. At this time, the sensor 25 transmits a signal to the control unit to notify the control that the early liquid crystal droplets are ejected from the nozzle N. When the control unit receives the signal from the sensor 25, the control unit determines that the liquid crystal droplets drip from the nozzle N. The control unit determines a temporary speed of 6.4 m/s as a suitable speed, wherein a liquid crystal droplet having a weight of 〇5 mg can be ejected from the nozzle n and dripped from the nozzle N. It is assumed that the weight of the liquid crystal droplet is 0.1 mg instead of 〇5 mg, and the nozzle inner diameter, the initial speed, and the fixed value are unchanged. In this case, as shown in FIG. 4 and FIG. 5, 14 201031468 even when the coating head nozzle 2 〇_ is applied at a temporary speed of 6.4 m/s, the liquid crystal droplet remains in the orifice of the nozzle N. It is emitted from the nozzle N. As a result, the sensor 25 does not transmit a signal to the control unit. When the control unit does not receive a signal from the sensor 25, the control unit determines that the liquid crystal droplet has not dripped from the nozzle N. The control unit repeats steps 1-2 by taking an initial speed of 4.8 m/s plus a fixed value of 1.6 m/s for a temporary speed of φ. Assume that the number of repetitions of step 1-2 is two. As a result, a temporary speed of 8 m/s (4.8 m/s + 1.6 m/s + 1.6 m/s) was obtained. The control unit instructs the coating head unit 20 to apply the liquid crystal amount through the nozzle N at a temporary speed of 8 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle n before the amount of liquid crystal is applied through the nozzle N. As shown in FIGS. 3 and 5, when the coating head unit 20 is applied with a liquid crystal amount at a temporary speed of 8 m/s, a liquid crystal droplet having a weight of l1 mg is ejected from the nozzle N. In this case, the liquid crystal droplet passes between the emitting portion 25a and the receiving portion 25b. The sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the nozzle N. When the control unit receives the signal from the sensor 25, the control unit determines that the liquid crystal droplets drip from the nozzle N. The control unit determines that the temporary speed of 8 m/s is appropriate 15 201031468 - speed, wherein a liquid crystal drop having a weight of 0.1 mg can be ejected from the nozzle N and dripped from the nozzle n. + Assume that a weight of .5 mg of liquid crystal droplets can be ejected from the nozzle N and the initial velocity from the nozzle (4) is 6.4 m/s instead of 4,8 m/s. As shown in FIGS. 3 and 5, when the coating head unit 20 is applied with a liquid crystal amount at an initial speed of 6.4 m/s, liquid crystal droplets are emitted from the nozzle N and dripped from the nozzle N. In this case, the liquid crystal droplet passes between the emitting portion 25a and the receiving portion 25b. The sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the mouth N. When the control unit is connected to the signal from the sense _ ,, the control unit determines that the liquid crystal droplet drops from the nozzle N. Now explain step 2-1. The control unit subtracts the initial value of 6.4 m/s from the fixed value of i.6 in/s and takes the temporary velocity of 4.8 m/s. Step 2-2 is now explained. The control unit instructs the coating head unit 2 to apply the liquid crystal amount through the nozzle N at a temporary speed of 4 8 m/s. The aperture of the cleaning unit nozzle N removes the liquid crystal droplets before the liquid crystal amount is applied through the nozzle N. Now explain steps 2-3. 16 201031468 As shown in Fig. 4 and Fig. 5, when the coating head unit 2 is coated with a liquid crystal amount at a temporary speed of 4 8 m/s, the liquid crystal droplets remain in the orifice of the nozzle N and are not emitted from the nozzle N. In this case, as shown in Fig. 5, no liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 does not transmit a signal to the control unit. As a result, although the control unit does not receive the signal from the sensor 25, the control unit determines that the liquid crystal droplet is not emitted from the nozzle N. The control unit determines the initial speed of 6.4 m/s as the appropriate speed because the liquid crystal droplets ejected from the nozzle can be detected at the initial speed of o 6.4 m/s and are emitted from the nozzle at the first temporary speed. The liquid crystal droplets were not detected. ^ It is assumed that a liquid crystal droplet having a weight of 0.5 mg can be ejected from the nozzle N and dripped from the nozzle N at an initial velocity of 8 m/s' instead of 4.8 m/s. As shown in Figs. 3 and 5, when the coating head unit 2 is coated with the liquid crystal amount at an initial speed of 8 m/s, the liquid crystal droplets are ejected from the nozzle N and dripped from the nozzle N. In this case, the liquid crystal droplets pass between the transmitting portion 25a and the receiving portion 2. The sensor 25 sends a message to control the fresh element to inform the control of the fresh liquid crystal drop. When the control, early connection (4) from the signal of sensing H 25, the control element determines the liquid crystal drop. Now explain step 2-1. The temporary speed is obtained at 1.6m/s. The control unit subtracts the initial speed of 8ni/s by a fixed value of 6.4m/s. 17 201031468 Now describe step 2-2. The control unit instructs the coating head unit 2 to apply the liquid crystal amount through the nozzle N at a temporary speed of six. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle N before the amount of liquid crystal is applied through the nozzle N. Now explain steps 2-3. ❿ As shown in Fig. 3 and Fig. 5, when the coating head unit 2 is coated with a liquid crystal amount at a temporary speed of 6.4 m/s, liquid crystal droplets are ejected from the nozzle and from the nozzle N·. In this case, the liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the nozzle N. When the control unit 70 receives the signal from the sensor 25, the control unit determines that the droplets drip from the nozzle N. The control unit repeats the step 2-2 by subtracting the initial value of 8 m/s from the fixed value of 1.6 m/s several times to obtain the temporary speed'. Assume that the number of repetitions of step 2-2 is two. As a result, a temporary velocity of 4.8 m/s (8 m/s to 1.6 m/s to 1.6 m/s) was obtained. The control unit instructs the coating head unit 2 to apply a liquid crystal amount through the nozzle N at a temporary speed of 4.8 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle N before the amount of liquid crystal is applied through the nozzle N. As shown in Figs. 4 and 5, when the coating head unit 2 is coated with a liquid crystal amount at a temporary speed of 4.8 m/s 18 201031468, the liquid crystal droplets remain in the orifice of the nozzle N and are not emitted from the nozzle N. In this case, as shown in Fig. 5, no liquid crystal droplets pass through the transmitting portion 2 to permit the receiving portion 25b. The sensor 25 does not transmit a signal to the control unit. Control the speed of a single mosquito operating speed of 6.4m / s, which is the final temporary speed from the side to the liquid crystal drop. It is assumed that the detecting unit is the electronic scale 30. Fig. 6 is a graph of experimental data, showing that the liquid crystal_weight changes as the speed of the coated liquid crystal increases. As shown in Fig. 1, the control unit instructs the first drive unit 14 and the second drive unit 17' to position the nozzle N of the coating head unit 20 above the gauge 31 of the electronic scale 3''. The nozzle N is positioned above the gauge disk 31 of the first drive unit 14 and the second drive unit sub-weigher 30. Assume that the initial speed is 6.4 m/s. As shown in Fig. 6, the control unit instructs the coating head unit 2 to transmit the liquid crystal droplets at the initial speed 6 through the nozzle n to emit the liquid crystal droplets of the weight from the nozzle n. The liquid crystal is dropped on the measuring disk 31. 19 201031468 Electronic scale 30 transmits signal to control unit 'Notice control unit weight 〇 5mg of liquid crystal droplets drip from nozzle N. The operation of determining the appropriate speed by the electronic scale 30 will not be described as it is the same as that of the sensor 25. Figure 8 is a flow diagram of a second method in accordance with the present invention for determining the appropriate speed at which the liquid crystal droplets are ejected from the nozzle and land on the panel regions defined on the mother substrate without being separated. The second method is now described to thereby determine the appropriate speed at which the coating head unit coats the amount of liquid crystal. False 5 and ^ (贞 | | § is sensing | § 25. Assume that the liquid crystal drop weight, initial velocity, and fixed values are 〇.5mg, 4.8m/s, and 1.6m/s, respectively. Refer to Figure 8 'When Detect When the measuring unit does not detect the liquid crystal droplet of the initial speed, the control unit performs: the first step, the temporary speed is taken by adding the initial speed to the fixed value, and the second step indicates that the coating head unit 2 is temporarily The speed is applied to the liquid crystal through the nozzle N; and in the third step, when the detecting unit detects the liquid crystal drop, 'determines the temporary speed to be an appropriate speed. When the detecting unit does not detect the liquid crystal droplet at the temporary speed, the control The unit repeats the second step 'the second step is repeated in which the initial speed plus the temporary speed of the fixed value is replaced by the previous temporary speed until the detecting unit detects the drop of the liquid crystal 20 201031468. Then, it is decided to detect the liquid crystal drop. The temporary speed is the appropriate speed. When the detecting unit detects the liquid crystal drop at the initial speed, the control unit determines the initial speed to be the appropriate speed. As shown in Fig. 4 and Fig. 5, when the coating head unit 2 is at the initial speed of 4.8. m/s ❹ painted When the liquid crystal amount is applied, 'the liquid crystal droplet remains in the orifice of the nozzle N and is not emitted from the nozzle N. In this case, as shown in Fig. 5, no liquid crystal droplet passes between the emitting portion 25a and the receiving portion 25b. The sensor 25 The signal is not transmitted to the control unit. When the control unit does not receive the signal from the sensor 25, the control unit determines that the liquid crystal droplet does not drip from the nozzle N. The first step is explained. The control unit will have an initial speed of 4.8 m/ s plus a fixed value of 1.6 m/s to obtain a temporary speed of 6.4 m/s. The second step will now be described. The control unit instructs the coating head unit 2 to apply a liquid crystal amount through the nozzle N at a temporary speed of 6.4 m/s. Before the nozzle N coats the liquid crystal amount, the cleaning unit removes the liquid crystal droplet from the orifice 21 201031468 of the nozzle N. The third step will now be described. As shown in Fig. 3 and Fig. 5, when the coating head unit 20 is at a temporary speed of 6.4 m/ s When the liquid crystal amount is applied, the liquid crystal droplets are emitted from the nozzle N and pass between the emitting portion 25a and the receiving portion 25b. At this time, the sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the nozzle N. When the control unit receives the signal from the sensor 25, it controls The unit determines that the liquid crystal droplet drops from the nozzle N. The control unit determines the temporary speed of 6 4 m/s as the appropriate speed, wherein the liquid crystal droplet with a weight of 55 mg can be ejected from the nozzle N and dripped from the nozzle N. The initial velocity of the liquid crystal droplets with a weight of 55 mg is 3.2 m/s instead of 4.8 m/s. As shown in Fig. 4 and Fig. 5, when the coating nozzle 2 is at an initial speed of 3 2 m/s, the amount of liquid crystal is applied. At this time, the liquid crystal droplet remains in the orifice of the nozzle N and is not emitted from the nozzle N. In this example, as shown in Fig. 5, no liquid crystal droplet passes between the emitter 2 and the receiving portion 25b. The sensor 25 does not. A signal is sent to the control unit. - When the control unit does not receive the signal from the sensor 25, the control unit determines that the liquid crystal droplet has not dripped from the nozzle N. 22 201031468 The first step is now explained. The control unit adds an initial speed of 3.2 m/s to a fixed value of 1.6 m/s to obtain a speed of 4.8 m/s. # Now explain the second step.

The cloth head unit 20 passes through the nozzle at a temporary speed of 4.8 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle N before the liquid crystal amount is applied through the nozzle N. The third step will now be explained. As shown in Fig. 3 and Fig. 5, when the coating head unit 2 is coated with a liquid crystal amount at a temporary speed of 4 m/s, the liquid crystal droplets remain in the orifice of the spray and are not emitted from the nozzles. In this example, no liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. At this time, the sensor 25 does not transmit a signal to the control unit. When the control unit does not receive a signal from the sensor 25, the control unit determines that the liquid crystal droplet has not dripped from the nozzle N. The control unit repeats the second step by subtracting the initial speed of 3 from the number-person's solid value of 1.6 m/s to obtain a temporary speed. Assume that the number of repetitions of the second step is two. As a result, a temporary speed of 64 m/s (3.2 m/s + 1.6 m/s + 1.6 m/s) was obtained. 23 201031468 The control unit instructs the coating head unit 20 to apply the liquid crystal amount through the nozzle N at a temporary speed of 6.4 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle n before the liquid crystal amount is applied through the nozzle N.

In this example, the liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the nozzle N. When the control unit receives the signal from the sensor 25, the control unit determines that the liquid crystal droplets drip from the nozzle N. 〇 The control unit determines a temporary speed of 6.4 m/s as the appropriate speed, wherein a liquid crystal drop having a weight of 0.5 mg can be ejected from the nozzle N and dripped from the nozzle n. It is assumed that a liquid crystal droplet having a weight of 0.5 mg can be ejected from the nozzle N and the initial velocity from the nozzle N is 6*4 in/s instead of 4*.8 rn/s. As shown in Figs. 3 and 5, when the coating head unit 2 is coated with the liquid crystal amount at an initial speed of 64 m/s, the liquid crystal droplets are ejected from the nozzle N and dripped from the nozzle n. In this example, the liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 24 201031468 sends a signal to the butterfly unit to notify the control solution that the droplets are dripped. When the control unit Weisi self-inducted 2S shouts, the (4) unit determines that the liquid crystal droplets drip from the nozzle N. The control unit determines the initial speed of 6.4 in/s as the appropriate speed. In the case where the weight of the liquid crystal droplet is 〇.丨mg instead of 〇5mg, the method of determining the speed of the field is not described because it is the same as the first method described above. The method of determining the appropriate speed using the electronic scale 30 instead of the sensor 25 will not be described because it is the same as the first method described above. Figure 9 is a flow chart of a third method in accordance with the present invention for determining the appropriate speed at which the liquid crystal droplets are ejected from the nozzle and land on the panel regions defined on the mother substrate without being splashed. The third method is now described to thereby determine the appropriate enthalpy speed at which the coating head unit coats the amount of liquid crystal. It is assumed that the detector is the sensor 25. Assume that the weight of the liquid crystal droplet is 〇.5 mg. The initial speed is such that the coating head unit 2 can apply a liquid crystal amount through the nozzle to cause the liquid crystal to drip within the speed range of the panel region. The speed range can be determined based on experimental data. This means that when the coating head unit 20 coats the liquid crystal amount at the initial speed, the liquid crystal droplets are ejected from the nozzle N and dripped from the nozzle n. Assume that the initial velocity and the fixed value are 6.4 m/s and 1.6 m/s, respectively. 25 201031468 Referring to FIG. 9, when the side of the single city pays (4) drops at the initial speed, the control unit performs: the first step, obtaining the temporary speed by subtracting the initial speed from the fixed value; and the second step, indicating the coating head The unit applies a liquid crystal amount through the nozzle at a temporary speed; and a third step 'determines the initial speed to be an appropriate speed when the side unit does not side to the liquid crystal droplet. When the detecting unit detects the liquid crystal drop at the temporary speed, the control unit repeats the second step, wherein the initial speed is subtracted from the temporary speed by a fixed number of times to replace the first temporary speed to repeat the second step until the detection The cell did not detect a liquid crystal drop. Then, it is decided to detect that the last temporary velocity of the liquid crystal droplet is an appropriate speed. As shown in FIGS. 3 and 5, when the coating head unit 2 is coated with the liquid crystal amount at an initial speed of 6 4 m/s, the liquid crystal droplets are emitted from the nozzle N and dripped from the nozzle N. In this example, the liquid crystal droplet passes between the emitting portion 25a and the receiving portion 25b. The sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the nozzle N. When the control unit receives the signal from the sensor 25, the control unit determines that the liquid droplet drip from the nozzle N. The first step will now be explained. Because the pre-measurement unit converges to drop the liquid crystal droplet from the nozzle N, the control unit subtracts the initial value of 6.4 m/s from the fixed value 丨6 m/s to obtain a temporary speed of 4 8 m/s. 26 201031468 The second step is now explained. The control unit instructs the coating head unit 2 to apply a liquid crystal amount through the nozzle N at a temporary speed of 4.8 m/s. The third step is now explained. As shown in Figs. 4 and 5, when the coating head unit 2 is coated with the liquid crystal 1 at a temporary speed of 4 m/s, the liquid crystal droplets remain in the orifice of the nozzle N and are not emitted from the nozzle N. In this example, as shown in Fig. 5, no liquid crystal droplets pass through the transmitting portion 2 to permit between the receiving portions 25b. The sensor 25 does not transmit a signal to the control unit. ~ When the control unit does not receive a signal from the sensor 25, the control unit determines that the liquid crystal drip is shot from the nozzle N. The control element determines the initial speed of 6.4m/s ', , and the appropriate S speed' because the liquid crystal droplets ejected from the nozzle at the initial speed of 6.4 m/s can be side-by-* at the first temporary speed from the nozzle. The liquid crystal droplets that were ejected were not detected. - It is assumed that the liquid crystal droplets of the weight #OJmg can be ejected from the nozzle N and dripped from the nozzle N at an initial velocity of 8 m/s instead of 6.4 m/s. As shown in Figs. 3 and 5, when the coating head unit 2 is coated at the initial speed, and the amount of liquid crystal is applied, the liquid crystal droplets are ejected from the nozzle N and dripped from the nozzle n. In this example, the liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The signal is sent to the control unit to inform the control unit that the liquid crystal is bribed. When the control unit receives the signal from the sense 25, (4) the single material determines the liquid crystal drop from the spray 27 201031468. The first step will now be explained. The control unit subtracts the fixed value 丨6m/s from the initial speed of 8m/s to obtain a temporary speed of 6.4m/s. The second step will now be explained. The control unit instructs the coating head unit 2 to apply a liquid crystal amount through the nozzle N at a temporary speed of 6 4 m/s. The cleaning unit removes the liquid crystal droplets from the opening of the nozzle n before the liquid crystal amount is applied through the nozzle N. The third step will now be explained. & As shown in FIGS. 3 and 5, when the coating head unit 20 applies a liquid crystal amount at a temporary speed of 6 m/s, liquid crystal droplets are emitted from the nozzle N and dripped from the nozzle N. In this example, the liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 transmits a signal to the control unit to notify the control unit that the liquid crystal droplets drip from the nozzle N. When the control unit receives the signal from the sensor 25, the control unit determines that the droplets drip from the nozzle N. The control unit repeats the second step by subtracting the initial value of 8 m/s from the fixed value of 1.6 m/s several times to obtain the temporary speed. Assume that the number of repetitions for the second step is 2 28 201031468 times. The result 'gets a temporary speed of 4.8111/5 (8111/5-1.6111/5-1.6111/5). The control unit instructs the coating head unit 20 to apply the liquid crystal amount through the nozzle N at a temporary speed of 4.8 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle n before the amount of liquid crystal is applied through the nozzle N. As shown in Fig. 4 and Fig. 5, when the coating head unit 20 is applied with a liquid crystal amount at a temporary speed of 4.8 m/s, the liquid crystal droplets remain in the orifice of the nozzle N and are not emitted from the nozzle n. In this case, as shown in Fig. 5, no liquid crystal droplets pass between the emitting portion 25a and the receiving portion 25b. The sensor 25 does not transmit a signal to the control unit. The control unit determines the temporary speed of 6.4 m/s as the appropriate speed, which is the last temporary speed at which the liquid crystal droplets are detected. Q In the case where the liquid crystal cell weight is 〇.lmg instead of 〇.5mg, the method of determining the appropriate speed is not described, as it is the same as the first method described above. The fourth method of determining the speed by the electronic scale 30 instead of the sensor 25 as the speed method for determining the appropriate speed of coating the liquid crystal unit by the coating head unit 2 is not described. It is assumed that the detecting unit is the electronic scale 30. Assume that the weight of the liquid crystal droplet is 〇 5 mg. 29 201031468 In the fourth method, the electronic mad head unit 20 (four) liquid " xiang 0 is used to determine the appropriate speed, where coating = 1 = 'so that the liquid crystal droplets are ejected from the mouth and drip on the panel, but not _ Check out other locations other than 31. In the fourth method, it is necessary to weigh the liquid crystal dripper 25 and cannot weigh the m mouth.
速度範圍可依據實驗^^康決定。此意味著當塗佈頭單元 20於初始速度塗佈液晶量時，液晶滴並未自喷嘴Ν射出並 自喷嘴Ν滴落。 假設初始速度及固定值分別為4.8m/s及1.6m/s。 當電子秤並未秤到液晶滴時，控制單元執行：第一步驟， 〇 藉由將初始速度加上固定值，而取得暫時速度；第二步驟，指 示塗佈頭單元於暫時速度透過喷嘴塗佈液晶量；以及第三步 驟，重複第二步驟，其中將初始速度加上數次固定值之暫時速 度取代先前暫時速度來重複第二步驟，直到液晶滴之重量由不 持續是固定而開始減少。 當液晶滴之重量由不持續是固定而開始減少時，決定自喷 嘴射出之液晶滴之重量為固定時之任何的暫時速度為適當速 度0 30 201031468 如圖1所示，當液晶滴從量測盤31減離破成碎片，使一 些，晶碎片滴落在量測盤31外的其他位置時’液晶滴量測的 重量不持續是固定的而開始減少。結果，留在量測盤31上之 液晶滴的重量比自喷嘴N射出的量還少。 如圖6所示’當塗佈頭單元20在大於8m/s之速度透過喷 嘴N塗佈液晶量時，重量〇 5mg的液晶滴麟量測盤，破 ❹ 成較小的液滴，其中-些落在量測盤31外的其他位置。當速 度自8m/s增加時，更多的液滴碎片落在量測盤31外的其他位 如圖6所示，當塗佈頭單元20於大於9.6m/s之速度透過 噴嘴N塗佈液晶量時，自喷嘴N射出之重量⑸吨的液晶滴 滅離面板區域破鱗#，—些破碎職落在面減域外的其他 付署。The speed range can be determined according to the experiment ^^康. This means that when the coating head unit 20 coats the liquid crystal amount at the initial speed, the liquid crystal droplets are not ejected from the nozzle and dripped from the nozzle. Assume that the initial velocity and the fixed value are 4.8 m/s and 1.6 m/s, respectively. When the electronic scale is not scaled to the liquid crystal drop, the control unit performs: a first step, obtaining a temporary speed by adding an initial speed to the fixed value; and a second step of instructing the coating head unit to apply the temporary speed through the nozzle The liquid crystal amount; and the third step, repeating the second step, wherein the initial speed is added to the temporary speed by a temporary speed instead of the previous temporary speed to repeat the second step until the weight of the liquid crystal droplet begins to decrease by not continuing to be fixed . When the weight of the liquid crystal droplet starts to decrease by not being fixed, it is determined that the temporary velocity at which the weight of the liquid crystal droplet emitted from the nozzle is fixed is an appropriate speed 0 30 201031468, as shown in Fig. 1, when the liquid crystal droplet is measured The disk 31 is broken away from the broken pieces, so that some of the crystal fragments are dropped on other places outside the measuring disk 31. 'The weight of the liquid crystal drop measurement does not continue to be fixed and starts to decrease. As a result, the weight of the liquid crystal droplets remaining on the measuring disk 31 is smaller than the amount emitted from the nozzle N. As shown in Fig. 6, when the coating head unit 20 coats the liquid crystal amount through the nozzle N at a speed of more than 8 m/s, the liquid crystal droplet measuring disk having a weight of 5 mg is broken into smaller droplets, wherein - Some of them fall outside the measuring disk 31. When the speed is increased from 8 m/s, more droplets fall on other positions outside the measuring disc 31 as shown in Fig. 6, when the coating head unit 20 is coated through the nozzle N at a speed of more than 9.6 m/s. When the amount of liquid crystal is used, the weight (5) tons of liquid crystal emitted from the nozzle N is broken from the panel area to break the scale #, and some of the broken positions are outside the area of the reduction.

The electronic scale cannot be scaled to the liquid crystal drop. At this time, the weight of the liquid crystal droplets measured was 〇mg (zero mg). The electronic scale 30 transmits a signal (4) unit, and informs the control unit of the liquid crystal droplets that the weight 1 is 0 mg (zero milligrams). Now, § 儿明弟一步骤 31 201031468 Although the control unit receives the signal from the electronic scale 30 indicating that the weight of the liquid crystal droplet is Omg, the control unit determines that the liquid crystal droplet does not drip from the nozzle N. Since the droplet weight remained fixed (〇mg) without being reduced, the initial speed of 4.8 m/s was added to the fixed value of 1.6 m/s to obtain a temporary speed of 6.4 m/s. The cleaning unit removes the liquid crystal droplets from the orifice of the nozzle N before the amount of liquid crystal is applied through the nozzle N. The second step will now be explained. The control unit indicates that the coating head unit 2 is at a temporary speed of 6 4 m/s, and the liquid crystal amount is applied through the nozzle N. The third step is now explained. As shown in FIGS. 3 and 6, when the coating head unit 2 is coated with a liquid crystal amount at a temporary speed of 64 m/s, the liquid crystal droplets are emitted from the nozzle N and land on the electronic scale 3G. The electronic scale has 30 kinds of heavy liquid crystal drops. The weight of the liquid crystal droplet is 〇 5 mg. The electronic department transmits a signal to the control unit to inform the control unit that the liquid crystal drop weight is 〇 5mg. The control unit determines the weight of the liquid crystal droplets of .5 mg from the spray drop. The measured liquid crystal droplet weight was increased from 〇 (zero) mg to Q 5 mg, and not less. Therefore, the initial step 4·8_ is added to the fixed value i of several times to obtain the speed at the time of 201031468, and the second step is repeated. The number of times the second step was repeated was 2 times. Therefore, the temporary % speed is 8ηι/8 (4.8ιη/5Ή.6ιη/8+1.6ηι/5;) 〇 The control unit instructs the coating head unit 20 to apply the liquid crystal amount through the nozzle 于 at a temporary speed of 8 m/s. As shown in FIGS. 3 and 6, when the coating head unit 2 is coated with the liquid crystal amount at a temporary speed of 8 n^s, the liquid crystal droplets are emitted from the nozzle N and land on the electronic scale 3''. Electric ❹ sub-weigher 30 subjects heavy liquid crystal drops. The weight of the liquid crystal droplet was 0.5 mg. The electronic scale 30 transmits a signal to the control unit to notify the control unit that the liquid crystal drop weight is 〇5 mg. The control unit determines that the liquid crystal droplets having a weight of 55 mg drip from the nozzle ν. The measured liquid crystal droplet weight (〇.5 mg) remained fixed and did not decrease. Therefore, the initial speed is 4.8 m/s and a fixed value of 16 ni/s is added several times to obtain a temporary speed, and the second step is repeated. The number of times the second step was repeated was 3 times. Therefore, the temporary speed was 9.6 m/s (4.8 m/s + 1.6 m/s + 1.6 m/s + 1, 6 m/cm). The control unit instructs the coating head unit 20 to apply the liquid crystal amount through the nozzle N at a temporary speed of 9.6 m/s. As shown in Fig. 3 and Fig. 6, when the coating head unit 2 is coated with a liquid crystal amount at a temporary speed of 9.6 m/s, the liquid crystal droplets are ejected from the nozzle N and land on the electronic scale. The electronic scale 30 weighs the liquid crystal droplets. The weight of the liquid crystal droplet is 〇 25 mg. The electronic scale 30 transmits a signal to the control unit, notifying the control unit that the liquid crystal drop weight is 0,25 mg in 201031468. The control unit determines that the weight of the liquid crystal droplet of .25 mg drops from the nozzle N. The measured liquid crystal droplet weight was reduced from a fixed 〇.5 mg to 〇.25 mg. So stop the second step. As shown in Fig. 6, when the coating head unit 20 was coated with a liquid crystal amount at a temporary speed of 6.4 m/s and 8 m/s φ, the measured liquid crystal droplet weight was fixed (0.5 mg). The control unit selects one of the temporary speeds of 6.4 m/s and 8 m/s to determine the appropriate speed. As shown in Fig. 6, when the coating head unit 20 was applied at a temporary speed of 8 m/s and a flow rate of 9 6 m/s, the measured liquid crystal droplet weight (〇 1 mg) was fixed. The control unit selects one of the temporary speeds of 8m/s and 9.6m/s to determine the appropriate speed. The fifth method of determining the appropriate speed at which the coating head unit 20 coats the liquid crystal amount will now be described. The fifth method is the same as the fourth method except that the liquid crystal droplet weight from the nozzle is determined to be an appropriate speed when the weight of the liquid crystal droplet emitted from the nozzle is fixed. 34 201031468 As shown in Fig. 6, when the coating head unit 20 is coated with a liquid crystal amount at a temporary speed of 64 m/s and 8 m/s, the amount of liquid (G. 5 mg) is fixed. The control unit determines the temporary speed of 6.4 m/s and an average speed of 8 m/s of 7.2 m/s for the appropriate speed. As shown in Fig. 6, the coating head unit 20 was fixed at a temporary speed gni/s and a liquid crystal amount of 9.6 m/s. The measured liquid crystal droplet weight (G.lmg) was fixed. The control unit 70 determines the temporary speed of 8 m/s and the average speed of 9.6 m/s of 8.8 m/s as the appropriate speed.
